What Is Acetec Used For?

Acetec contains enalapril maleate and belongs to a group of medicines called ACE inhibitors. It is prescribed to help manage two main heart-related conditions.

Primary Uses

Acetec is used to lower high blood pressure (hypertension) and to treat heart failure. For hypertension, it helps prevent serious complications like stroke, heart disease, and kidney failure. For heart failure, it can slow disease progression, reduce hospital stays, and may help patients live longer.

How It Works

Acetec works by widening your blood vessels, which allows blood to flow through them more easily. This means your heart doesn’t have to pump as hard to move blood around your body. During exercise or physical activity, your heart may cope better and you may not get short of breath as easily.

Good to know: Acetec is not addictive and can be safely taken long-term as prescribed by your doctor.

How to Take Acetec

Your doctor will determine the right dose for you based on your condition and other medications you may be taking. Take Acetec at the same time each day for best results.

Dosage Instructions

For high blood pressure: Most patients start with 5 mg once daily, though some may need a lower starting dose. The dose may be increased based on your blood pressure response, with most patients taking between 10-40 mg daily. For heart failure: The usual starting dose is 2.5 mg once daily, which may be increased up to 20 mg daily, taken once or divided into two doses. Swallow tablets with a glass of water. It doesn’t matter if you take it before or after food.

What If You Miss a Dose?

If you miss a dose, take it as soon as you remember, then continue with your normal schedule. If it’s almost time for your next dose, skip the missed dose and take your next dose at the regular time. Don’t take a double dose to make up for the missed one.

Important: Never stop taking Acetec or change your dose without checking with your doctor first, even if you feel better.

Alcohol & Driving

Acetec can cause dizziness and light-headedness, which may be worsened by alcohol and can affect your ability to drive or operate machinery safely.

Alcohol

If you drink alcohol, dizziness or light-headedness may be worse. Tell your doctor about your alcohol consumption as they may advise you to limit your intake.

Driving and Operating Machinery

Acetec may cause dizziness or light-headedness, especially after your first dose or when your dose is increased. Make sure you know how you react to Acetec before driving, operating machinery, or doing anything that could be dangerous if you feel dizzy.

Storage

Store Acetec below 25°C in a cool, dry place away from moisture, heat, and sunlight. Keep tablets in the original blister pack until it’s time to take them – don’t transfer to another container as they may become soft and crumbly. Store in a locked cupboard at least 1.5 meters above ground, away from children. Take any unwanted or expired medicine to a pharmacy for safe disposal.

Overdose Information

If you take too many Acetec tablets, you will likely feel light-headed, dizzy, or may faint. If you suspect an overdose, seek immediate medical attention. Call the Poisons Information Centre (Australia: 13 11 26), contact your doctor, or go to the nearest hospital emergency department immediately, even if there are no obvious symptoms.
